The length of the outline curve of any surface of single lens elementwithin the range of maximum effective half diameter affects itsperformance in correcting the surface aberration and the optical pathdifference between the rays in each field of view. The longer outlinecurve may lead to a better performance in aberration correction, but thedifficulty of the production may become higher. Hence, the length of theoutline curve (ARS) of any surface of a single lens element within therange of the maximum effective half diameter has to be controlled, andespecially, the proportional relationship (ARS/TP) between the length ofthe outline curve (ARS) of the surface within the range of the maximumeffective half diameter and the central thickness (TP) of the lenselement to which the surface belongs on the optical axis has to becontrolled. For example, the length of the maximum effective halfdiameter outline curve of the object-side surface of the first lenselement is denoted as ARS11, and the central thickness of the first lenselement on the optical axis is TP1, and the ratio between both of themis ARS11/TP1. The length of the maximum effective half diameter outlinecurve of the image-side surface of the first lens element is denoted asARS12, and the ratio between ARS12 and TP1 is ARS12/TP1. The length ofthe maximum effective half diameter outline curve of the object-sidesurface of the second lens element is denoted as ARS21, and the centralthickness of the second lens element on the optical axis is TP2, and theratio between both of them is ARS21/TP2. The length of the maximumeffective half diameter outline curve of the image-side surface of thesecond lens element is denoted as ARS22, and the ratio between ARS22 andTP2 is ARS22/TP2. The proportional relationships between the lengths ofthe maximum effective half diameter outline curve of any surface of theother lens elements and the central thicknesses of the lens elements towhich the surfaces belong on the optical axis (TP) are denoted in thesimilar way.

The length of ½ entrance pupil diameter outline curve of any surface ofa single lens element especially affects the performance of the surfacein correcting the aberration in the shared region of each field of view,and the performance in correcting the optical path difference among eachfield of view. The longer outline curve may lead to a better function ofaberration correction, but the difficulty in the production may becomehigher. Hence, the length of ½ entrance pupil diameter outline curve ofany surface of a single lens element has to be controlled, andespecially, the proportional relationship between the length of ½entrance pupil diameter outline curve of any surface of a single lenselement and the central thickness on the optical axis has to becontrolled. For example, the length of the ½ entrance pupil diameteroutline curve of the object-side surface of the first lens element isdenoted as ARE11, and the central thickness of the first lens element onthe optical axis is TP1, and the ratio thereof is ARE11/TP1. The lengthof the ½ entrance pupil diameter outline curve of the image-side surfaceof the first lens element is denoted as ARE12, and the central thicknessof the first lens element on the optical axis is TP1, and the ratiothereof is ARE12/TP1. The length of the ½ entrance pupil diameteroutline curve of the object-side surface of the first lens element isdenoted as ARE21, and the central thickness of the second lens elementon the optical axis is TP2, and the ratio thereof is ARE21/TP2. Thelength of the ½ entrance pupil diameter outline curve of the image-sidesurface of the second lens element is denoted as ARE22, and the centralthickness of the second lens element on the optical axis is TP2, and theratio thereof is ARE22/TP2. The ratios of the ½ HEP outline curves onany surface of the remaining lens elements of the optical imagecapturing system to the central thicknesses of that lens element can becomputed in similar way.

The height of optical system (HOS) may be reduced to achieve theminimization of the optical image capturing system when |f1|>|f6|.

When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| satisfy the aforementionedconditions, at least one of the second through fifth lens elements mayhave a weak positive refractive power or a weak negative refractivepower. The weak refractive power indicates that an absolute value of thefocal length of a specific lens element is greater than 10. When atleast one of the second through fifth lens elements has the weakpositive refractive power, the positive refractive power of the firstlens element can be shared by it, such that the unnecessary aberrationwill not appear too early. On the contrary, when at least one of thesecond and third lens elements has the weak negative refractive power,the aberration of the optical image capturing system can be slightlycorrected.

The sixth lens element may have negative refractive power, and theimage-side surface thereof may be a concave surface. With thisconfiguration, the back focal distance of the optical image capturingsystem may be shortened and the system may be minimized. Besides, atleast one surface of the sixth lens element may possess at least oneinflection point, which is capable of effectively reducing the incidentangle of the off-axis rays, thereby further correcting the off-axisaberration.

Second Embodiment

Please refer to FIG. 2A, FIG. 2B and FIG. 2C. FIG. 2A is a schematicview of the optical image capturing system according to the secondembodiment of the present invention. FIG. 2B shows the longitudinalspherical aberration curves, astigmatic field curves, and opticaldistortion curve of the optical image capturing system of the secondembodiment, in the order from left to right. FIG. 2C is a transverseaberration diagram at the position of 0.7 HOI on the image plane of theoptical image capturing system of the second embodiment. As shown inFIG. 2A, in the order from an object side to an image side, the opticalimage capturing system includes a first lens element 210, a second lenselement 220, a third lens element 230, an aperture stop 200, a fourthlens element 240, a fifth lens element 250, a sixth lens element 260, anIR-bandstop filter 280, an image plane 290, and an image sensing device292.

The first lens element 210 has positive refractive power and is made ofplastic material. The first lens element 210 has a concave object-sidesurface 212 and a convex image-side surface 214, and both object-sidesurface 212 and image-side surface 214 are aspheric.

The second lens element 220 has negative refractive power and is made ofplastic material. The second lens element 220 has a concave object-sidesurface 222 and a concave image-side surface 224, and both object-sidesurface 222 and image-side surface 224 are aspheric. The object-sidesurface 222 has one inflection point.

The third lens element 230 has negative refractive power and is made ofplastic material. The third lens element 230 has a convex object-sidesurface 232 and a concave image-side surface 234, and both object-sidesurface 232 and image-side surface 234 are aspheric. The object-sidesurface 232 has one inflection point.

The fourth lens element 240 has positive refractive power and is made ofplastic material. The fourth lens element 240 has a convex object-sidesurface 242 and a convex image-side surface 244, and both object-sidesurface 242 and image-side surface 244 are aspheric. The object-sidesurface 242 thereof has one inflection point.

The fifth lens element 250 has positive refractive power and is made ofplastic material. The fifth lens element 250 has a convex object-sidesurface 252 and a convex image-side surface 254, and both object-sidesurface 252 and image-side surface 254 are aspheric. Both of theobject-side surface 252 and the image-side surface 254 have oneinflection point.

The sixth lens element 260 has negative refractive power and is made ofplastic material. The sixth lens element 260 has a concave object-sidesurface 262 and a concave image-side surface 264. As a result, the backfocal length thereof can be reduced, such that the size of the opticalimage capturing system can be kept small. In addition, the image-sidesurface 264 of the sixth lens element 260 has one inflection point,which can reduce the incident angle of the off-axis rays. Therefore, theoff-axis aberration can be mitigated.

The IR-bandstop filter 280 is made of glass material and is disposedbetween the sixth lens element 260 and the image plane 290. TheIR-bandstop filter 280 does not affect the focal length of the opticalimage capturing system.

The contents in Tables 3 and 4 below should be incorporated into thereference of the present embodiment.

As a result, the backfocal length thereof can be reduced, such that the size of the opticalimage capturing system can be kept small. In addition, the incidentangle of the off-axis rays can be reduced. Therefore, the off-axisaberration can be mitigated.

The IR-bandstop filter 380 is made of glass material and is disposedbetween the sixth lens element 360 and the image plane 390. TheIR-bandstop filter 380 does not affect the focal length of the opticalimage capturing system.

Fourth Embodiment

Please refer to FIG. 4A, FIG. 4B and FIG. 4C. FIG. 4A is a schematicview of the optical image capturing system according to the fourthembodiment of the present invention. FIG. 4B shows the longitudinalspherical aberration curves, astigmatic field curves, and opticaldistortion curve of the optical image capturing system of the fourthembodiment, in the order from left to right. FIG. 4C is a transverseaberration diagram at the position of 0.7 HOI on the image plane of theoptical image capturing system of the fourth embodiment. As shown inFIG. 4A, in the order from an object side to an image side, the opticalimage capturing system includes a first lens element 410, a second lenselement 420, a third lens element 430, an aperture stop 400, a fourthlens element 440, a fifth lens element 450, a sixth lens element 460, anIR-bandstop filter 480, an image plane 490, and an image sensing device492.

The first lens element 410 has negative refractive power and is made ofplastic material. The first lens element 410 has a convex object-sidesurface 412 and a concave image-side surface 414, and both object-sidesurface 412 and image-side surface 414 are aspheric.

The second lens element 420 has negative refractive power and is made ofplastic material. The second lens element 420 has a convex object-sidesurface 422 and a concave image-side surface 424, and both object-sidesurface 422 and image-side surface 424 are aspheric. The object-sidesurface 422 has one inflection point.

The third lens element 430 has negative refractive power and is made ofplastic material. The third lens element 430 has a convex object-sidesurface 432 and a concave image-side surface 434, and both object-sidesurface 432 and image-side surface 434 are aspheric. The object-sidesurface 432 has one inflection point.

The fourth lens element 440 has positive refractive power and is made ofplastic material. The fourth lens element 440 has a convex object-sidesurface 442 and a convex image-side surface 444, and both object-sidesurface 442 and image-side surface 444 are aspheric. The object-sidesurface 442 has one inflection point.

The fifth lens element 450 has positive refractive power and is made ofplastic material. The fifth lens element 450 has a convex object-sidesurface 452 and a convex image-side surface 454, and both object-sidesurface 452 and image-side surface 454 are aspheric. The image-sidesurface 454 has one inflection point.

The sixth lens element 460 has positive refractive power and is made ofplastic material. The sixth lens element 460 has a concave object-sidesurface 462 and a convex image-side surface 464. As a result, the backfocal length thereof can be reduced, such that the size of the opticalimage capturing system can be kept small. In addition, the image-sidesurface 464 thereof has one inflection point, so the incident angle ofthe off-axis rays can be reduced. Therefore, the off-axis aberration canbe mitigated.

The IR-bandstop filter 480 is made of glass material and is disposedbetween the sixth lens element 460 and the image plane 490. TheIR-bandstop filter 480 does not affect the focal length of the opticalimage capturing system.

Fifth Embodiment

Please refer to FIG. 5A, FIG. 5B and FIG. 5C. FIG. 5A is a schematicview of the optical image capturing system according to the fifthembodiment of the present invention. FIG. 5B shows the longitudinalspherical aberration curves, astigmatic field curves, and opticaldistortion curve of the optical image capturing system of the fifthembodiment, in the order from left to right. FIG. 5C is a transverseaberration diagram at the position of 0.7 HOI on the image plane of theoptical image capturing system of the fifth embodiment. As shown in FIG.5A, in the order from an object side to an image side, the optical imagecapturing system includes a first lens element 510, a second lenselement 520, a third lens element 530, an aperture stop 500, a fourthlens element 540, a fifth lens element 550, a sixth lens element 560, anIR-bandstop filter 580, an image plane 590, and an image sensing device592.

The first lens element 510 has negative refractive power and is made ofplastic material. The first lens element 510 has a convex object-sidesurface 512 and a concave image-side surface 514, and both object-sidesurface 512 and image-side surface 514 are aspheric. The object-sidesurface 512 has one inflection point.

The second lens element 520 has negative refractive power and is made ofplastic material. The second lens element 520 has a concave object-sidesurface 522 and a convex image-side surface 524, and both object-sidesurface 522 and image-side surface 524 are aspheric. The object-sidesurface 522 and the image-side surface 524 both have two inflectionpoints.

The third lens element 530 has positive refractive power and is made ofplastic material. The third lens element 530 has a convex object-sidesurface 532 and a convex image-side surface 534, and both object-sidesurface 532 and image-side surface 534 are aspheric.

The fourth lens element 540 has positive refractive power and is made ofplastic material. The fourth lens element 540 has a convex object-sidesurface 542 and a convex image-side surface 544, and both object-sidesurface 542 and image-side surface 544 are aspheric. The image-sidesurface 544 has one inflection point.

The fifth lens element 550 has negative refractive power and is made ofplastic material. The fifth lens element 550 has a convex object-sidesurface 552 and a concave image-side surface 554, and both object-sidesurface 552 and image-side surface 554 are aspheric. The object-sidesurface 552 has one inflection point, while the image-side surface 554has two inflection points.

The sixth lens element 560 has positive refractive power and is made ofplastic material. The sixth lens element 560 has a convex object-sidesurface 562 and a convex image-side surface 564. As a result, the backfocal length thereof can be reduced, such that the size of the opticalimage capturing system can be kept small. In addition, the image-sidesurface 564 thereof has one inflection point, so the incident angle ofthe off-axis rays can be reduced, and the off-axis aberration can bemitigated.

The IR-bandstop filter 580 is made of glass material and is disposedbetween the sixth lens element 560 and the image plane 590. TheIR-bandstop filter 580 does not affect the focal length of the opticalimage capturing system.
